Gly-dependency was studied using a luciferase reporter gene system. Maximal reporter gene expression happened in the presence of low Gly concentrations. RT-qPCR showed that in the presence of Gly (≥1 mM), expression of the gene was downregulated. Growth in the presence of 0.1 mM Gly led to the production of a full-length transcript. We conclude that the Gly riboswitch in S. pyogenes represses gene expression in the presence of high Gly concentrations. %L 570 %9 theses %9 Text %9 Hochschulschrift %R 10.18453/rosdok_id00002093 %U http://rosdok.uni-rostock.de/resolve/urn/urn:nbn:de:gbv:28-diss2018-0087-1 %U https://nbn-resolving.org/urn:nbn:de:gbv:28-diss2018-0087-1 %U https://d-nb.info/1293652717/34 %U https://doi.org/10.18453/rosdok_id00002093
